N designates a discharge-outlet for Waste material in the open condenser.

In the regular operation of this improved apparatus forliquor evaporation and distillation the cold air is forced through the pipes G G,and discharged from the perforated outlet or coil H into the hot liquid, causing mechanical ehullition to assist the effect of the heat applied. As the cold air passes through the heated liquor,it absorbs heat and moisture and, expanding, carries the moisture upward with it and passes out through the gooseneck to the condenser for liquefaction and preservation. To assist this operation the special blast-outlet at I in the goose-neck is provided. This new supply of air takes up aportion of the vapor passing from the evaporator, renders the mass of vapor less dense, and assists in the free movement ofthe whole to the condenser.

For taking water, moisture, or dampness from fruits, vegetables, and other solids, the

cold air mingles with the heated surrounding, air, relieves it of a portion of its vapor, and

develops a current through and out of the evaporator chamber or apartment and its connecting goose-neck to the condenser, where the vapor is condensed and run out through disdischarge N.

What I claim as new,and desire to secure by Letters Patent, is-

1. In an evaporating apparatus, the combi nation, with the evaporator chamber or apartment B, having exhaust-pipe or goose-neck I, of heater coil or pipe 0, blowing'engine or fan E, accumulator andclarifier F, cold-airpipe system G. cold-air-discharge pipe or coil H, condenser J, and cold-water pipe K, snhv stantially as and for purposes specified.

2. In an evaporating apparatus, the combination, with the evaporator chamber or apartment B, having exhaust-pipe or goose-neck I, of heater coil or pipe O,blowing engine or fan E, accumulator and clarifier F, cold-air-pipe system G, cold-air-discharge pipe or coil H, condenser J, and closed coil M, substantially as and for purposes specified.

3. In an evaporating apparatus, the combination of the blowing-engine or fan E, pipe system G G, accumulator F, evaporator chamber or apartment B, having a contracted goose-neck, and the branch cold-air pipe g,discharging into the contracted portion of the goose-neck I. substantially as and for purposesset forth.

4. In an evaporating apparatus, the combination of the blowing-engine or fan E, accumulator and clarifier F,cold-air-pipe system G G, cold-air-discharge pipe or coil H, heater coil or pipe 0, evaporator chamber or apartment B, having a contracted gooseneck, and the branch cold-air pipe 9, discharging into the contracted portion of the goose-neck I,

substantially as and for purposes set forth.

5. In an evaporating apparatus, the combination of the blowing-engine or fan E, accumulator or olarifier F, cold-airpipe system. G G, cold-air-discharge pipe or coil H, heater coil or pipe 0, evaporator chamber or apartment =B, having a contracted goose-neck, branch cold-air pipe g,discharging into the contracted portion of the goose-neck I, condenser J, and cold-water-supply pipe K, substantially as and for the purposes set forth.
